Fine fescue taxa differ in their field establishment rate but it is unclear if this due to differences germination or seedling growth rate. Research at Purdue University quantified seed morphology, vigor, and vigor among 30 cultivars of fine (FF) (Festuca spp.). Strong creeping red (STCRF) rubra ssp. rubra), slender (SLCRF) (F. littoralis), Chewings commutata), hard brevipila), sheep ovina) wer...
این تحقیق به منظور بررسی روش های کلاسیک و آغازگرهای اختصاصی در ردیابی قارچ های اندوفیت در گیاهان علفی تیره گندمیان صورت گرفت که در راستای این هدف بیست جدایه قارچ از چهار میزبان مرتعی bromus tomentellus،lolium prenne ،festuca pratensis وfestuca arundinacea جداسازی گردید. نمونه ها ابتدا از طریق رنگ آمیزی با محلول رنگی رز بنگال از نظر حضور قارچ اندوفیت آزمایش شدند، سپس نمونه های حاوی قارچ روی مح...
در این پژوهش، قارچ های اندوفیت از غلاف برگ و بذور میزبان های گیاهی festuca arundinacea، f. pratensis، f. ovina، bromus tomentellus melica persica و lolium prenne جداسازی گردید. خصوصیات مرفولوژیکی این قارچ ها روی محیط کشت های مختلف مورد بررسی قرار گرفت. اکثر جدایه های بررسی شده در این تحقیق از نظر مرفولوژیکی با توصیف عمومی جنسacremonium در بخش albo-lanosa و جنس neotyphodiumجدا شده از یک گونه ...
Introduction Medical intervention in allergies has broadened its perspective, also focusing in the quality of life of patients. Patients are instructed, before using pharmacotherapy agents, to avoid the causal agent. Objective This study aims to analyze the sensitization profile of patients with allergic complaints and identify possible characteristics specific to each age group and gender. Met...
Mycotoxins are secondary metabolites produced by fungal species that have harmful effects on mammals. The aim of this study was to assess the content of mycotoxins in fresh-cut material of selected forage grass species both during and at the end of the growing season. We further assessed mycotoxin content in subsequently produced first-cutting silages with respect to the species used in this st...
Optical and thermal remote sensing data were acquired at ground level over several turfgrass species under different soil and irrigation treatments in northern Colorado, USA. Three vegetation indices (VIs), estimated based on surface spectral reflectance, were sensitive to the effect of reduced water application on turfgrass quality. The temperature-based Grass Water Stress Index (GWSI) was als...
BACKGROUND Grasses release the most widespread aeroallergens with considerable sensitization rates, while different species produce several pollen concentration peaks throughout the season. This study analyzed the prevalence of grass species in three different European city areas and compared the flowering period of these species with daily pollen concentrations and the symptom loads of grass p...
